explaining lost

Easter is one of those in-between holidays, at least in my house. Definitely more important than Arbor Day but not nearly as important as Thanksgiving. So several family members didn't come to Easter dinner yesterday, which means I got to talk to a couple of people a lot instead of several people just a little. Since I work for The Most Awesome TV Blog in the Universe (TM), the conversation turned to television, specifically to 'Lost.'

I don't remember exactly how the conversation went (I wish I had a tape recorder running), but it was very close to this:

Sister: Oh, you watch 'Lost?'Me: Yeah, it's great!

Sister: So what's going on on it?Me: _______?
Sister: I mean, the last time I saw it they were on an island. That guy who was on 'The Practice' was there.Me: Michael Emerson. He's a great actor.
Sister: So what has happened since then?
